This time it looks like a bug.</p> <p>I've got these includes<br /> <code><br /> #include &lt;stdlib.h&gt;<br /> #include &lt;string&gt;<br /> #include &lt;sstream&gt;<br /> #include &lt;Wire.h&gt; //I2C library<br /> #include &lt;I2C_eeprom.h&gt;<br /> #include &lt;TinyGPS.h&gt;<br /> #include &lt;track.h&gt;<br /> </code></p> <p>And a function using std::string like this:</p> <p><code><br /> //Pad the incoming long with 0 to length<br /> std::string pad(long num, int length) {<br /> std::string number;<br /> std::stringstream strstream;<br /> strstream &lt;&lt; num;<br /> strstream &gt;&gt; number;</p> <p> int str_length = number.length();<br /> for (int i = 0; i &lt; length - str_length; i++)<br /> number = "0" + number;<br /> return number;<br /> }<br /> </code></p> <p>This should all work, were it not that the cpp file generated (by the IDE, I suppose) is missing the std:: namespace for the function declaration. The code generated looks like this:<br /> <code><br /> #include &lt;stdlib.h&gt;<br /> #include &lt;string&gt;<br /> #include &lt;sstream&gt;<br /> #include &lt;Wire.h&gt; //I2C library<br /> #include &lt;I2C_eeprom.h&gt;<br /> #include &lt;TinyGPS.h&gt;<br /> #include &lt;track.h&gt;</p> <p>#include "WProgram.h"</p> <p>void setup();<br /> void loop();<br /> string pad(long num, int length);<br /> </code></p> <p>Obviously, omitting the std:: namespace will not work. Is there a quick workaround for this? I tried to manually declare everything, hoping that the IDE would pick that up and not try to do it itself... </p>
